Data_A New Species of Hyporheic Corethrella Coquillett from North America (Diptera: Corethrellidae)
Description
Larval and adult data sets from a study conducted on Bull Creek, MO (southwest of Ozark, MO) from October 2017 to October 2018 by Nathan C. Dorff. Accompanies A New Species of Hyporheic Corethrella Coquillett from North America (Diptera: Corethrellidae). The larva of Corethrella kipferi sp. n. occupies hyporheic habitat regardless of perennial surface flow in two close locales in the Ozark Mountains in Christian County, Missouri, USA. This represents the first capture and identification to species-level of Corethrella in the hyporheic zone and the only description of a larva from the rotunda species group. The larvae appear to be obligate hyporheic dwellers with no representatives collected in concurrent benthic samples from riffles of the perennial stream. The female adult and fourth instar larva are described and illustrated using photomicrographs and line drawings. We describe what is known of the natural history of the new species and infer its phylogenetic placement within the genus.
